Hello,
First of all, thanks for a detailed description, many clients are simply careless. Based on what I can read here, it all sounds perfect to me (and for me), but it is missing pictures to describe the style and level of quality you're looking for.
I am a digital painter specializing in realistic style and fantasy settings but with varying styles and qualities, easily adjusted to your needs and budget. Though my artwork tends to be in higher detail / realism than the standard children book that you can find on the market, some people are looking for exactly that - to be different, so I am making this bid.
I've worked on several books in recent past and I know well the standards and rules for books and ebooks. I love interpreting other's peoples ideas and stories into a stunning visual. But also I don't mind participating in deciding things together with author, I even read the whole books in the past in order to understand the characters and emotions.
PS: sorry for making fun of your 8th rule
